1.2V Serial NOR Flash

The W25QxxND 1.2V series parts have performance identical to the popular 3V and 1.8V families of serial flash with the added benefit of saving power. They are offered in 2mm x 3mm USON8, narrow 150mil SOP8, 6x5mm WSON 8-pin packages and KGD (Known Good Die) which provide designers with the convenience of designs in space constrained battery based applications for mobile, wearable, IoT and other demanding designs that call for low power in tiny packages. While the 1.2V series products are popular for power savings, the extended 1.5V can save battery cost by utilizing only one battery compared to similar solutions using two batteries in series to offer 3V designs.

The First Ultra-Low-Voltage

New 1.2V is the next standard voltage

The newest members of the Winbond SpiFlash family are the industry’s lowest voltage standard, dual and quad Serial Peripheral Interface (SPI) and Quad Peripheral Interface (QPI) NOR Flash products offering major power savings not known in the industry before.

Better Power Consumption

Increase battery run-time / Power saving in active mode of 33%

The reduced power usage in both active and stand-by modes offered by the W25QxxND series enables system designers to increase battery run-time between charges, or to reduce the size and weight of the battery.

The W25Q80ND, an 8Mbit NOR Flash IC operating from a 1.2V supply, offers a typical power saving in active mode of 33% over the equivalent 1.8V part.

Simplify The System Power Domain

Reduce power consumption by turning off NOR while sleeping / Reduce system BOM cost by simple power domains

The new devices also provide additional advantages. The first is the power circuit which benefits from reduced noise coupling in the traces connecting the memory to the host SoC or processor, a direct result of the reduced power that they carry. This can help ease the requirement to implement noise mitigation measures such as shielding, and to improve the performance of noise-sensitive elements of the circuit.

The other principal advantage of the 1.2V devices is the potential, over time, to simplify the power circuit.
